Integrated operating and fault indicator.
Fault forwarding possible via potential-free contacts.
The power supply (70 W) converts mains voltage to system voltage and charges the
batteries.
The DC 24 V system voltage is electrically isolated.
For the supply of consumers in accordance with EN 54-4 and VdS.
The output voltage is short-circuit-proof and battery charging is current-limited.
Must not be connected in parallel.
The battery charge voltage is regulated with temperature compensation.
A jumper can be used to switch the mains voltage from AC 230 V to AC 115 V.
Monitoring of mains voltage and the batteries
● A failure of the AC 230 V supply voltage or a higher internal battery resistance are
detected and an error message is generated.
Uninterruptible power supply
● If the mains voltage fails, the supply switches automatically from mains operation to
battery operation.
Protecting the battery against total discharge
● When the final voltage is reached, the battery switches off automatically.
Use
The power supply kit FP120-Z1 is for the following use:
● Standalone power supply for decentralized supply to external devices (DC 24 V) in
accordance with EN 54-4 and VdS.
Possible configuration
● Installation of various battery types from 7 Ah to 17 Ah
● Installation of input/output module FDCIOxxx
● Installation of a TS35 U-rail to mount several modules, such as FDCIOxxx/Z3B171
